What advantage does the R/2R ladder DAC have over a binary- weighted- input DAC?
A) The virtual ground is eliminated and the circuit is therefore easier to understand and troubleshoot.
B) It uses only two different resistor values.
C) It is much easier to analyze its operation.
D) It has fewer parts for the same number of inputs.

Quizplus · Accepted Answer

The R/2R ladder DAC uses only two different resistor values (R and 2R), which simplifies its design and manufacturing compared to a binary-weighted-input DAC that requires a wide range of resistor values for different bits.
